@foone oh if you wanted to be a broadcast engineer - Belden 8451 audio cable.
Every old-ish radio station has at least one place where someone ran 120VAC to some control relays, an RF relay, or an on-air light on 8451. Bonus: it goes through an unprotected 66 block somewhere mid-run.
A broadcast engineer rite of passage is to be the "lucky" one who finds the Spicy Audio Cable by thinking it's abandoned piffle and tries to cut it out and winds up with a fireworks show
